Formula:
Al4(SO4)(OH)10 · 4H2O
Colour:
Colourless, yellow, white; colourless in transmitted light.
Crystal System:
Monoclinic
Name:
From the type locality, Felsöbánya, Hungary (now Baia Sprie, Romania).
A hydrated aluminium sulfate first described by Kenngott in 1853 (as felsöbányite). However, the mineral was earlier observed around 1841/42 by Haidinger in the collection of the Imperial and royal Chamber of Mining, Vienna (Papp, 2004).
Later Bannister & Hollingworth (1948) described a white compact mineral with conchoidal fracture and a white plastic clay-like appearance from Old Lodge Pit, Northamptonshire, England, UK, and gave it the name basaluminite (a BASic sulfate of ALUMINum).
Farkas & Pertlik (1997) showed that basaluminite is identical with felsőbányaite, and basaluminite was discredited by IMA in 2006 (Burke, 2006). The name felsőbányaite has priority over "basaluminite" which wasn't named until 1948.
May originate as a dehydration product of hydrobasaluminite.
